Smartphone Batteries Are Finally Evolving, and I Couldn't Be Happier
1 min read
Summary
Smartphones have reached a plateau in terms of battery technology despite having advanced in other features
Lithium-ion batteries, whilst successful, are not fit for thefuture of smartphones
Silicon-carbon batteries offer 10 times the energy density of current lithium-ion batteries
That means phones could eventually become much thinner whilst still offering excellent battery life
These batteries also offer slower degradation, meaning a phone would last longer before needing to be replaced
The reason silicon batteries are not mainstream is because of the cost of production, and the fact silicon swells when charging, which can compromise the battery cell
However, silicon is abundant in nature, and the production process should become cheaper over time, and researchers have found a way to minimize the swelling risk through the addition of carbon, offering more stability
